Astronomers concerned by plan to give NASA ground control

Remaking NASA. Astronomers ponder a really long-range vision for NASA.

NASA - CR - 190715 Ground Systems Development Environment ( GSDE ) Interface Requirements and Prototyping Plan

This report describes the data collection and requirements analysis effort of the GSDE Interface Requirements study. It identifies potential problems in the interfaces among applications and processors in the heterogeneous systems that comprise the GSDE. It describes possible strategies for addressing those problems. It also identifies areas where further research and prototyping are needed to ...

Instrumentation: astronomers look to nanotechnology.

The nanoscale and hydrophobic structures of the network enable the otherwise water-absorbing cotton to repel water nearly as efficiently as the lotus leaf. Furthermore, the treated fabrics are stronger and more resistant to tears. Nanotube concentrations of over 2% in the applied emulsion...

control of the optical properties of nanoparticles by laser fields

در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...

Ground Based Rainfall Measurements at the NASA Wallops Flight Facility

The rainfall measurements collected at the NASA Wallops Flight Facility during the first 4 months of 2001 were analyzed to study the small-scale variability of rainfall and to evaluate the instruments performance with respect to each other. The instrument platform included impact and optical type disdrometers, tipping bucket rain gauges, and sonic anemometers. An X-band polarametric (X-POL) rad...
